• What is the cause and solution for SAP error message FINS_RECON369 - Duplicate entry in table BSAK_BCK: &1 message(s) ?

  The SAP error message FINS_RECON369 indicates that there is a duplicate entry in the table BSAK_BCK. This table is used for storing accounting documents that have been cleared, and the error typically arises during the reconciliation process or when trying to post transactions that involve clearing accounts.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Duplicate Clearing Entries: There may be multiple entries in the BSAK_BCK table for the same document number and fiscal year, which violates the uniqueness constraint of the table.

  If you have identified duplicates, you may need to delete the unnecessary entries. This should be done with caution and ideally in a test environment first.
  Use transaction code SE14 to manage database table entries if necessary.
  
  
  
  Check for Data Consistency:
